1. HDDDf2. Memory Free3. How to correctly identify the number of CPUs and the number of cores with Linux commands Cat/proc/cpuinfo |grep Physical |sort-u |wc-l This command is to view the number of CPUs. Basis of judgment:1. CPUs with the same core ID are Hyper-threading of the same core.2. CPUs with the same physical ID are the same CPU-encapsulated thread or cores.English version:1.Physical ID and Core ID is not necessaril

Recently, a timestamp system was written to record some important time nodes of each module in the system. Getting the kernel escalation timestamp is through the process polling, but found that the process in the actual running CPU utilization is very high, which is a dead loop in reading the device files, this thought is due to read system calls too frequent reasons.Then write a test program, which is just an empty loop. It turns out that the

Summer may be you are high game or movie, suddenly the computer blue screen crashes, and then most people will think directly is not the problem of the system, and then reload the system, if it is a system problem, after the system reload the problem will be solved. If still often appear blue screen, it is not a software problem, then can only be hardware problems, most people face this situation will be sent to overhaul, and overhaul when the staff most often encountered is the

Most computer users have encountered the problem of excessive CPU temperature, in the end, how much of the CPU temperature is normal? Today small make up for everyone to clean up the desktop computer and laptop CPU temperature too high solution, take a look! Cpu In general, the

CPU Tuning How the CPU processes data: 1: Batch processing, sequential processing requests. (Less switching times, larger throughput) 2: time-sharing processing. (like "exclusive", throughput is small) (Time slices, the request is divided into one piece of time, a piece of the CPU processing) we are using x86 is this architecture 3: Real-time processing. Batch p

Http://blog.csdn.net/nineday/archive/2007/12/11/1928847.aspx Under Linux, CPU utilization is divided into user state, System State and idle state, respectively, the CPU in user state execution time, system kernel execution time, and idle system process execution time, the sum of the three is CPU total time, when no user process, system process, etc. need to execu

Article Title: cpu affinity settings. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. # Include # Include # Include # Include Int main (int argc, char * argv []) { Int num = sysconf (_ SC _NPROCESSORS_CONF ); Int created_thread = 0; Int myid; Int I; Int j = 0; Cpu_set_t mask; Cpu_set_t get; If (argc! = 2) {

The most intuitive benefit of binding a process to the CPU is to reduce cache synchronization and switching between CPUs, increase the hit rate of the CPU cache, and improve the efficiency of the Code.From the CPU architecture, NUMA has independent local memory, the nodes can be exchanged between the modules to connect and information interaction, so each

Partial reprint 51942281The iostat command is used to monitor system input and CPU usage. It is characterized by the reporting of disk activity statistics, as well as the reporting of CPU usage. like Vmstat, Iostat also has a weakness, that is, it cannot analyze a process in depth, only the overall situation of the system. Iostat Monitoring I/O subsystemThe IOSTAT is an abbreviation for I/O statistics (inpu

Malfunction Abnormal: computer black screen, overclocking, automatic restart, temperature is too high and so on these are the CPU socket contact bad caused. Here is a specific analysis of these situations. Failure resolution: One, CPU pins caused by bad CPU contact When you find that the CPU is not in contact with t

From a technical point of view, there is no essential difference between bulk and boxed CPUs, at least in terms of quality. Theoretically, there is no gap in performance, stability, and overclocking potential between boxed and bulk products, but there are certain differences in warranty. The difference between bulk and boxed from a technical point of view, there is no essential difference between bulk and boxed CPUs, at least in terms of quality. For CPU
